There are several formats for phone numbers: local, domestic and international.
The domestic phone number format can be used for calls within the same country as your rented phone number. For example, if you rented a US number, you do not need to add +1 to recipient numbers from the US.
However, we recommend using E.164 formatting for all prospect phone numbers in Reply. This is an internationally-recognized standard phone number format that will help to ensure the deliverability of calls and SMS messages across the globe.
How does E.164 work?
E.164 formatting entails the following:
- A + (plus) sign (replacing the international call prefix like 011)
- The international country calling code
- Local area code
- Local 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
E.164 Mobile Numbers:
In a number of countries, local dialing may require the addition of a '0' in front of the subscriber number. With E.164 formatting, this '0' should 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:
