# Formatting International Phone Numbers
Salesmate strongly encourages
[E.164 phone number formatting](https://en.wikipedia.org/wiki/E.164)
for all phone numbers both in the ‘to’ and ‘from’ fields. This is an internationally-recognized standard phone number format that will help to ensure deliverability of calls and SMS messages across the globe.Instead of reaching out from Salesmate using an
[International Call Prefix](https://en.wikipedia.org/wiki/List_of_international_call_prefixes#Countries_by_international_prefix)
like 011, simply use an E.164 formatted phone number.
### **E.164 Phone Number Formatting** E.164 formatting for phone numbers entails the following:
A + (plus) signInternational Country Calling codeLocal Area codeLocal Phone number
For example, here’s a US-based number in standard local formatting:**(415) 555-2671**
Here’s the same phone number in E.164 formatting:\*\*+14155552671 \*\*
\*\* In the UK, and many other countries internationally, local dialing may require the addition of a '0' in front of the subscriber number. With E.164 formatting, this '0' must usually be removed.For example, here’s a UK-based number in standard local formatting: 020 7183 8750
Here’s the same phone number in E.164 formatting:\*\*+442071838750 \*\*\*
