Extract Phone Numbers

What it finds

• US and Canada: (555) 123-4567, 555-123-4567, 555.123.4567, 1-800-555-0199, 5551234567
• International: +44 20 7946 0958, +33 1 23 45 67 89, +44 (0)20 7946 0958, 07946 095842
• Extensions: x12, ext. 12 and extension 12 are kept, written as x12

The same number written two ways, like (555) 123-4567 and 555-123-4567, is listed once, the first way it appears. Extract as digits only removes spaces, dashes, dots and brackets, keeping a leading +, which is the format most spreadsheets and contact apps import best.

What it skips

Dates (2026-10-03, 10/3/2026), IP addresses, prices, decimals, ZIP codes and other short numbers, and codes that mix letters and numbers, like invoice or order numbers. A run of digits with no spaces or dashes is only counted when it’s 10 or 11 digits long, so most ID numbers are left out.

Phone numbers are written so many ways that no extractor is perfect: glance over the list before using it. Numbers written with letters (1-800-FLOWERS) aren’t found.

Next steps

Remove duplicates across several lists, compare with another list to find new contacts, or make it comma separated. Because extraction happens in your browser, contact lists stay on your computer.
