Test data for QA

Test phone number generator

Generate test mobile and landline numbers for Argentina, Mexico, Spain, the US, Chile, Uruguay, Colombia, Brazil and Peru, in local, international and E.164 format.

Generated numbers are fictitious data for software testing: they have a valid format and check digit, but do not belong to real people, accounts or cards. Do not use them for real transactions.

How it works

Pick the country, line type (mobile or landline) and how many you need. Real area codes are used (for the US, numbers use the 555-01xx range reserved for fiction where possible) and each number has the correct length.

Every number is shown in local, international and E.164 format (+5491123456789), the format most APIs such as WhatsApp or Twilio expect. Export the list to CSV or JSON.

Frequently asked questions

What is E.164?

The international phone number standard: a + followed by the country code and the national number with no spaces or symbols, up to 15 digits.

Do the generated numbers exist?

They may, since they use real formats. Use them only in test environments and never call or text them.
