Frequently Asked Questions
▶How do I extract phone numbers from an email?
Copy the email content — including the body, signature, and any forwarded messages — then paste it into NumSwift. It instantly detects and extracts all phone numbers from the text in under one second using Google's libphonenumber library. Numbers from 200+ countries are supported, and duplicates across the email body and signature are automatically removed.
▶Does it work with email signatures?
Yes. NumSwift reliably extracts phone numbers from email signatures regardless of layout. It handles international formats like +44 20 7946 0958, North American formats like (555) 123-4567, compact formats like 5551234567, and entries that include labels such as "Mobile:" or "Direct:". All 15+ commonly used phone number formats are recognized.
▶Can it handle long email threads?
Absolutely. You can paste an entire email thread — including replies, forwards, and quoted messages — and NumSwift finds every unique phone number across the full conversation. Because the same contact signature often repeats in each reply, automatic deduplication ensures each number only appears once in the final list, no matter how many times it was quoted.
▶Which email clients are supported?
NumSwift works with any email client including Gmail, Outlook, Apple Mail, Yahoo Mail, Thunderbird, Fastmail, and any other client that lets you copy email text. Simply copy the email text and paste it in — NumSwift is source-agnostic and processes plain text only, so the originating email client does not matter.
