Phone Number Extractor
The phone number extractor scans text for numbers written in international (+44, +1) and common national formats, including spaced, dashed, dotted and bracketed groupings. Results can be de-duplicated and normalised to digits only.

How to use the Phone Number Extractor
- Paste the text containing phone numbers.
- Raise the minimum digit count if short reference numbers are being picked up by mistake.
- Turn on normalisation if you need digits only for an import.
- Copy or download the list.
Example
Input
Call +1 (212) 555-0100 or 07700 900123.
Output
+1 (212) 555-0100 07700 900123
Common use cases
- Collecting contact numbers from a signature block or a document.
- Auditing an export to see which records contain a phone number.
- Cleaning up numbers before importing them into a CRM.
Limitations and things to watch for
- Phone numbers have no single universal format, so matching is heuristic. It recognises international prefixes, bracketed area codes and the usual separators, but it cannot know whether a run of digits is a phone number, an order reference or an account number. Raise the minimum digit count to reduce false positives.
- Numbers are not validated against national numbering plans, so an impossible number will still be returned if it looks like one.
- Extension suffixes such as "ext. 42" are not captured as part of the number.
Frequently asked questions
Which formats does it recognise?
International numbers beginning with a plus and a country code, numbers with bracketed area codes, and numbers separated by spaces, hyphens or full stops — the formats that appear in real documents and signatures.
Why did it pick up a number that is not a phone number?
Any digit sequence of the right length and shape can match. Increasing the minimum digit count usually removes reference numbers and dates from the results.
Does it check whether the number is valid?
No. Validating against national numbering plans needs a maintained database and is beyond what a pattern match can do. The tool finds candidates, not confirmed numbers.
