What Gets Checked
No account needed. Nothing is stored or shared.
Structure Validation
Checks whether the number is valid for its country. Each country has different rules for mobile and landline formats, digit counts, and prefix patterns.
Country and Region
Identifies the country and region from the dialling code. Supports 200+ countries and territories, and outputs the number in clean E.164 format.
Number Type
Detects whether a number is mobile, landline, toll-free, or VOIP. Useful for SMS campaigns since messages can only be delivered to mobile numbers.

Frequently asked questions
Yes. No account, no credit card, no sign-up. You can validate up to 50 numbers per batch for free. The only limit is the batch size.
Any common format works. You can paste international numbers with or without spaces (+1 305 555 7890), numbers with brackets and dashes ((212) 555-1234), or plain digits (4155556789). Set the default country at the top of the tool and local numbers will be interpreted correctly. Numbers with a + prefix are always treated as fully international regardless of the default country selected.
The tool checks whether the number is structurally valid for its country, identifies the country and region, and detects the number type (mobile, landline, toll-free, VOIP). It does not verify whether a number is currently active or assigned to a real SIM. No tool can do that without a live carrier lookup, which involves real network queries and is a different category of service entirely.
Your numbers are sent to our server to run the validation, but nothing is stored or logged. We do not save your contact list, share it with third parties, or use it in any way beyond returning your results.
If you would rather nothing left your computer at all, the free Bulk Phone Validator app for Windows does the same checks completely offline.
This online tool handles up to 50 numbers per batch. For larger lists, the free Bulk Phone Validator app for Windows checks a whole Excel or CSV file at once with no cap, and runs offline.
And once the list is clean, QuickText is what sends the texts.
