Generate fictitious phone numbers for the US/Canada, UK and Brazil. US and UK numbers use ranges reserved for fiction. National, international and E.164 formats, batches and a format validator.
Real phone numbers in a demo or a test can reach real people. This tool avoids that where it can: US and Canadian numbers use 555-0100 to 555-0199, the block the North American Numbering Plan reserves for fiction, and UK numbers use the ranges Ofcom sets aside for drama, such as 020 7946 0xxx and 07700 900xxx. Brazil has no reserved range, so Brazilian numbers have a valid format with a real DDD and may belong to someone, and the tool says so. Each number comes in national, international and E.164 form.
In the North American Numbering Plan, 555-0100 to 555-0199 are set aside for fictional use, so a number like (212) 555-0142 will not reach a household. In the UK, Ofcom lists ranges it keeps out of allocation for TV and radio drama, one block of 1,000 numbers per area code, plus 07700 900000 to 900999 for mobiles.
Brazil has no such range. A number with a valid DDD and a plausible body can belong to a real person, so use it only in tests that never dial.
National is how people dial at home, international adds the country code, and E.164 is the compact form for databases and APIs: a plus sign, the country code and the digits with no spaces, up to 15 digits in total.
The validator checks structure only. It never calls a carrier, so it cannot tell if a number is active, and a valid result does not mean the number is in use.
Paste the code into your HTML and the tool shows up on your page, without J-Kit's navigation and ads. It still runs in the browser of whoever visits your site.

US/Canada numbers (555-0100 to 555-0199) and UK numbers (Ofcom drama ranges) are reserved so they are not allocated to customers. Brazilian numbers are different: Brazil has no reserved range, so a valid-format number may belong to a real person.
