## Phone Number Lookup

URL: https://www.realvalidito.com/phone-lookup/

### What is Phone Number Lookup?

Phone number lookup is a service that checks a US or Canada phone number against live carrier data and returns validation status, line type, carrier name, and geographic information - all in under 1 second. RealValidito's phone number lookup is the industry standard for businesses that need to verify contact data before outbound calls, SMS campaigns, or CRM updates.

Unlike simple format validation (regex checks), RealValidito's phone number lookup queries real carrier databases to confirm whether a number is currently active and carrier-assigned - not just whether it follows the correct digit pattern.

### What Data Does Phone Number Lookup Return?

- **valid** - Whether the number is properly formatted (NANPA compliant) and carrier-assigned
- **active** - Whether the number has been assigned to a carrier (does not mean it is currently in use by a person)
- **line_type** - mobile | landline | voip | toll_free | prepaid | pager | unknown
- **carrier** - Current serving carrier (e.g. Verizon, AT&T, T-Mobile, Rogers, Bell)
- **carrier_original** - The carrier the number was originally issued to before any porting
- **ported** - Whether the number has been ported between carriers
- **country_code** - +1 (US/Canada)
- **state** - US state or Canadian province abbreviation
- **city** - City associated with the number's area code and exchange
- **timezone** - IANA time zone identifier (e.g. America/New_York, America/Toronto)

### How Phone Number Lookup Works

1. Submit any 10-digit US or Canada phone number in any format (dashes, parentheses, spaces, leading 1 all accepted)
2. RealValidito normalizes the number and queries live carrier routing databases
3. The system verifies the number against the North American Numbering Plan (NANPA) and confirms carrier assignment
4. Results are returned in under 1 second as a JSON response

### Phone Number Lookup Use Cases

- **Lead validation**: Validate phone numbers collected via web forms before they enter your CRM
- **SMS campaign eligibility**: Identify mobile numbers (the only line type eligible for SMS marketing)
- **CRM data enrichment**: Append carrier, line type, and time zone to existing contact records
- **TCPA compliance**: Determine line type before autodialed or pre-recorded calls
- **Fraud prevention**: Flag VoIP and prepaid numbers that are commonly associated with fraud
- **Bulk database cleaning**: Upload a CSV of phone numbers and validate the entire list in one operation

### Phone Number Lookup FAQ

**What is the difference between valid and active?**
Valid means the number conforms to NANPA formatting rules and falls within an assigned number block. Active means the number has been assigned to a specific carrier. A number can be valid but inactive if the number block exists but the specific number has not yet been assigned to a subscriber.

**Does phone number lookup work for mobile and landline numbers?**
Yes. RealValidito validates any type of US or Canada phone number: mobile, landline, VoIP, toll-free, prepaid, and pager numbers. The line_type field tells you exactly which type the number is.

**Does validation actually call or ring the phone number?**
No. RealValidito queries carrier routing databases only. No call is placed, no ring is generated, and the number's owner is never notified.

**What format should phone numbers be in?**
Any standard 10-digit format is accepted - with or without dashes, parentheses, spaces, or a leading 1. Examples: 2125551234, 212-555-1234, (212) 555-1234, 12125551234.

**What is number portability (LNP)?**
Local Number Portability allows subscribers to keep their phone number when switching carriers. RealValidito detects ported numbers and returns the current serving carrier, not the original issuing carrier - ensuring your carrier data is always up to date.

**Can I validate phone numbers in bulk?**
Yes. Upload a CSV file containing up to 50,000 phone numbers. RealValidito processes the list and returns an enriched file with validation results appended to each row.

## DNC Lookup - Do Not Call Checker

URL: https://www.realvalidito.com/dnc-lookup/

### What is DNC Lookup?

DNC lookup (Do Not Call lookup) is a service that screens whether a US phone number appears in our DNC screening data or is associated with known TCPA litigants and professional plaintiffs. Businesses use DNC lookup before making outbound calls or sending SMS messages to verify compliance and avoid TCPA violations.

The Telephone Consumer Protection Act (TCPA) requires businesses to scrub their contact lists against the National DNC Registry every 31 days. Calling a DNC-registered number without a valid exemption can result in fines of $500 (negligent violation) to $1,500 (willful violation) per call. Class-action lawsuits multiplying these penalties across thousands of contacts have resulted in multi-million dollar settlements.

### What is the National Do Not Call Registry?

The National Do Not Call Registry is a free database maintained by the FTC where US consumers can register their phone numbers to opt out of unsolicited telemarketing calls. Businesses making outbound calls for commercial purposes must check their contact lists against the registry at minimum every 31 days and suppress all registered numbers.

### What Data Does DNC Lookup Return?

- **dnc_registered** - Whether the number appears in our DNC screening data
- **litigation_risk** - Whether the number is associated with known TCPA plaintiffs or plaintiff attorneys
- **phone** - Normalized 10-digit number
- **status** - safe | dnc | high_risk

### DNC Checker vs. DNC Scrubber

A DNC checker verifies one phone number in real time - ideal for validating numbers at the point of entry in a form or CRM. A DNC scrubber processes an entire contact list in bulk before a campaign launch. RealValidito supports both workflows: single-number checks via the DNC Lookup API and full-list scrubbing via bulk CSV upload.

### What Databases Does RealValidito Check?

RealValidito screens numbers against:
1. The US National Do Not Call Registry (federal DNC, maintained by the FTC)
2. Known TCPA plaintiff databases - phone numbers belonging to professional plaintiffs and plaintiff attorneys who actively seek TCPA violations to generate lawsuit settlements

Note: RealValidito's DNC lookup checks federal DNC and litigation risk data. It does not check individual state-level DNC registries.

### DNC Lookup FAQ

**How often should I run a DNC check?**
The FTC requires businesses to scrub contact lists against the National DNC Registry at least every 31 days. Best practice is to run a DNC check before every campaign, regardless of when the list was last scrubbed.

**What is the difference between the DNC registry and TCPA litigants?**
The DNC registry contains numbers registered by consumers who want to stop telemarketing calls. TCPA litigant databases contain numbers belonging to professional plaintiffs who intentionally register numbers and wait for businesses to call them, then file TCPA lawsuits for profit. RealValidito screens against both.

**What are the TCPA fine amounts?**
$500 per negligent violation, $1,500 per willful violation. Each call to a DNC-registered number is a separate violation. Class-action cases have resulted in settlements exceeding $10 million.

**Can I integrate DNC lookup into my dialer or CRM?**
Yes. The DNC Lookup API accepts a 10-digit number and returns a JSON response in under 1 second. It can be integrated into any CRM, auto-dialer, web form, or marketing platform via HTTP requests.

**Does DNC lookup cover cell phone numbers?**
Yes. The TCPA prohibits autodialed or pre-recorded calls to mobile numbers without prior express written consent, regardless of whether the number is on the DNC list. Cell phone numbers on the DNC list face double restrictions - DNC registry status and mobile-specific TCPA consent requirements.

**How do I scrub a list of thousands of numbers?**
Upload a CSV file through RealValidito's bulk validation interface. The system processes all numbers against the DNC registry and litigation risk databases and returns a results file with DNC status appended to each record.

## Gender Lookup by Name

URL: https://www.realvalidito.com/gender-lookup/

### What is Gender Lookup by Name?

Gender lookup by name is the process of predicting the likely gender associated with a first name by comparing it against large databases of names with known gender associations and computing a probability score. RealValidito's gender detection tool processes any first name in under 1 second, returning a gender classification (male, female, or unknown) along with a confidence score (0-100%).

Gender lookup does not determine personal identity. It is used for CRM personalization, email marketing segmentation, and database quality control - specifically to identify and flag names that have no recognizable gender association (e.g. random strings like "asdfgh" or clearly offensive entries).

### What Data Does Gender Lookup Return?

- **gender** - male | female | unknown
- **confidence** - 0-100 percentage score reflecting statistical certainty
- **name** - Normalized form of the input name
- **valid_name** - true/false (whether the name is recognized as a real human first name)

### How Gender Lookup Works

1. Submit a first name in any format (capitalized, lowercase, mixed)
2. RealValidito normalizes the name - handling spelling variants, diacritics, and transliterations
3. The normalized name is cross-referenced against a database of millions of records spanning 180+ countries
4. A confidence score is computed based on how consistently the name maps to a single gender across regions
5. Results are returned in under 1 second

### Gender Lookup Use Cases

- **Email personalization**: Address customers by correct salutation (Mr./Ms./Mx.) using only the first name field
- **CRM segmentation**: Separate contacts by gender for targeted product or messaging campaigns
- **Database hygiene**: Flag entries where the "first name" field contains random strings, numbers, or offensive content - valid_name: false indicates an entry that should be reviewed
- **Bulk enrichment**: Upload a CSV of first names and receive gender assignments for an entire database in one operation

### Coverage

RealValidito's gender lookup covers first names from 180+ countries, including names in Latin, Cyrillic, Arabic, Chinese, Hebrew, and other scripts. It is effective for both common English names and diverse international name sets.

### Gender Lookup FAQ

**How accurate is gender lookup by name?**
For common English, Spanish, French, and German names, accuracy exceeds 95%. For rare, regional, or cross-cultural names, accuracy varies. Every result includes a confidence score so you can filter by certainty threshold - for example, auto-accept results above 80% and route lower-confidence records for manual review.

**What is the confidence score?**
The confidence score (0-100) reflects how consistently the name is used by one gender across the database. A score of 95 for "Maria" as female means 95% of people named Maria in the database are female. A score of 55 for an ambiguous name like "Alex" reflects roughly equal male/female usage.

**Can I look up gender for non-English names?**
Yes. Names from 180+ countries across multiple scripts are supported. Names like "Fatima", "Hiroshi", "Aleksandra", and "Kwame" all return accurate results with regional cultural context taken into account.

**Does gender lookup work with full names?**
The API is optimized for first names. If a full name is submitted, the system parses the first token as the given name. For best accuracy, submit the first name field separately.

**What does valid_name: false mean?**
It means the submitted name has no recognized gender association in the database - either because it is a random string, a number, a nickname with no gender signal, or an offensive word. This flag is useful for identifying data quality issues in name fields.

## ZIP Code Lookup - Postal Code Validator

URL: https://www.realvalidito.com/zipcode-lookup/

### What is ZIP Code Lookup?

ZIP code lookup is the process of validating a US ZIP code or Canadian postal code and retrieving the geographic data associated with it - including city, state or province, county, area code, time zone, and GPS coordinates. RealValidito's ZIP code validator processes any US or Canada postal code in under 500 milliseconds via a REST API call or free online tool.

### Supported Formats

- **US ZIP codes**: 5-digit (e.g. 10001) and ZIP+4 (e.g. 10001-0034)
- **Canadian postal codes**: Standard A1A 1A1 format (e.g. M5V 2T6, R3B 3A1)

### What Data Does ZIP Code Lookup Return?

- **valid** - Whether the code is a recognized, active US or Canadian postal code
- **zip** - Normalized ZIP or postal code
- **city** - Primary city or municipality name
- **state** - State or province abbreviation (e.g. NY, CA, ON, BC)
- **state_full** - Full state or province name (e.g. New York, Ontario)
- **county** - County name (US only)
- **area_code** - Telephone area code associated with the location
- **timezone** - IANA time zone identifier (e.g. America/New_York, America/Vancouver)
- **dst** - Whether the location observes Daylight Saving Time
- **latitude** - GPS latitude coordinate
- **longitude** - GPS longitude coordinate
- **country** - US or CA

### How ZIP Code Lookup Works

1. Submit a US ZIP code or Canadian postal code in any standard format
2. RealValidito validates the code format and checks it against USPS and Canada Post reference databases
3. The system confirms whether the code is valid and currently active
4. City, state/province, county, area code, time zone, and GPS coordinates are returned in a single JSON response in under 500 ms

### ZIP Code Lookup Use Cases

- **Address form auto-fill**: When a user types their ZIP code, automatically populate city and state fields
- **Shipping validation**: Verify postal codes before generating shipping labels
- **Geographic targeting**: Segment customers by city, state, county, or time zone using only a postal code
- **Time zone scheduling**: Determine the correct local time for a contact when scheduling calls or messages
- **Database enrichment**: Append city, state, and coordinates to existing records that contain only a ZIP code
- **E-commerce checkout**: Validate postal codes in real time before order submission

### ZIP Code Lookup FAQ

**Does RealValidito support Canadian postal codes?**
Yes. All Canadian postal codes in A1A 1A1 format are supported. The API returns province, city, and geographic data for Canadian codes using the same endpoint as US ZIP codes.

**What is the difference between a ZIP code and a ZIP+4?**
A standard US ZIP code is 5 digits. A ZIP+4 appends a 4-digit suffix (e.g. 10001-0001) identifying a more specific delivery segment. RealValidito accepts both formats; the +4 extension is stripped and the base 5-digit code is used for geographic lookups.

**How current is the ZIP code database?**
RealValidito's reference data is regularly updated from USPS and Canada Post official sources. All 42,000+ active US ZIP codes and all valid Canadian postal code patterns are covered.

**Can I validate ZIP codes in bulk?**
Yes. Upload a CSV file of postal codes through RealValidito's bulk validation interface. The system validates every code and appends city, state, county, time zone, and coordinates to each record. Download the enriched output in CSV format.

**How fast does the API respond?**
Under 500 milliseconds for the vast majority of requests - fast enough for real-time form validation and inline checkout verification.
