# Mobile Number Standardization

> Standardize mobile numbers in MoEngage to E.164 format for reliable SMS and WhatsApp delivery. Configure country codes and number formatting.

# Overview

As a marketer, you can set up a standard format for submitting mobile numbers to MoEngage and select the required details, such as adding + and country code so that MoEngage can submit mobile numbers in E.164 format, i.e., +countrycodemobilenumber to WhatsApp and SMS connectors.

We recommend using one of the following formats to store a mobile number in MoEngage. Examples of a mobile number to be sent to a customer in the US / Canada are mentioned below:

* [E.164 Format](/docs/user-guide/settings/advanced-settings/e164-phone-number-format) i.e. +countrycodemobilenumber, for example, +1999999999
* Numbers without a + (plus ) sign, for example, 19999999999
* Mobile numbers without country code and + sign, for example, 999999999

<Info>
  MoEngage currently adds +91 as the default country code for all mobile numbers when submitting them to SMS and WhatsApp connectors.
