The standard format for Philippine callsigns is 2×3 – where 2 stands for the prefix letters (4D-4I or DU-DZ), and 3 stands for the suffix letters, both of which are assigned and regulated by the National Telecommunications Commission. A suffix can have as much as three (3) characters, and as little as one (1).
The NTC assigns prefixes depending on the privileges of the amateur license or for special events:
A district number is assigned to a station depending on its location. The Philippines is divided into nine (9) separate amateur districts.
A special event station may also be issued a district number different from those listed above (e.x. 100).
