The +9 prefix is associated with the country calling codes for several nations, primarily in Asia, rather than representing a single, standalone international dialing code. It signifies that a country's full international dialing code begins with the digit '9'.
Many countries have international dialing codes that start with the digit '9'. Based on typical categorizations of telephone numbering plans, countries whose codes begin with +9 are often grouped within a "Region 9." This region designates a set of geographic areas whose national telephone systems use dialing codes commencing with the digit '9'.
For instance, some notable countries whose international dialing codes begin with +9 include:
| Country Name | Country Code |
|---|---|
| India | +91 |
| Iran | +98 |
| Iraq | +964 |
When making an international call to one of these nations, the complete country code (e.g., +91 for India), followed by the specific area code and local telephone number, must be dialed to successfully connect the call.
