How to Use the +255 Country Code: A Guide for SMBs and Startups

What Is the 255 Country Code?

+255 is the country code for Tanzania, used when dialing Tanzanian phone numbers from outside the country. To ensure calls and messages connect properly, it's essential to use the correct format.

Here’s the standard format for Tanzanian numbers:

• Country Code: +255
• Area/Mobile Code: Varies by region or carrier (e.g., 22 for Dar es Salaam, 75 for Vodacom)
• Number Format: +255 XX XXX XXXX

Tanzania also includes the autonomous region of Zanzibar, which uses the same country code and similar formatting conventions.

Common Pitfalls in Tanzanian Number Formatting

Incorrect number formatting can lead to failed connections, misrouted messages, or reduced pickup rates. Below are common issues businesses face when dialing Tanzanian numbers:

• Omitting the +255 code: International calls fail if the country code isn’t included.
• Using a local format internationally: Writing numbers like 0754 123 456 instead of +255 754 123 456 causes confusion and failed dials.
• Leading zeros: The ‘0’ that appears in local Tanzanian numbers (e.g., 0754) must be removed when using the international format.
• Inconsistent formatting across tools: Differences between CRM, VoIP, and messaging apps can lead to syncing and contact lookup issues.
• Wrong spacing or symbols: Including extra spaces, dashes, or brackets may confuse systems not built to handle formatting inconsistencies.
• Standardizing your Tanzanian contact data in the international format helps ensure better delivery rates and professional communication.
