Validate email, phone, URL, credit card, IP address, and other common formats.
Data validation is essential for forms, databases, and data processing. The Format Validator checks if text matches expected formats for common data types including emails, phone numbers, URLs, credit cards, IP addresses, and more. Invalid data causes problems: email validation prevents typos that make contact impossible, phone validation ensures dialing works, URL validation prevents broken links, credit card validation prevents payment errors. Validating data improves data quality and user experience. Our Format Validator supports: email addresses (RFC standard format), phone numbers (multiple formats and country codes), URLs and web addresses, credit card numbers (validates format and checksum), IPv4 and IPv6 addresses, postal codes, dates, and custom formats. Web developers use validators to ensure user input is valid before processing. Businesses use validators to clean imported data. Data analysts use validators to identify formatting errors. Customer service uses validators to verify customer information accuracy. Simply paste text and the validator checks format instantly, showing whether it's valid or suggesting corrections for common errors.
Valid emails have format: user@domain.extension, with specific rules for allowed characters.
This tool validates format only. Verifying existence requires sending verification email.
Checksum is a mathematical calculation on card number that detects typos. Valid cards pass checksum validation.
The tool checks for valid URL format, but doesn't verify if the URL actually works (site might be offline).
