Why Do Police Use ‘Ida’ Instead of Just ‘I’?

Because just saying “I” over radio can sound like “A” or “Y.” Ida nails it—no mix-ups, no repeats. It’s clear, sharp, and quick.

• Ida is the APCO spelling alphabet term for I, used by U.S. law enforcement.
• India is the NATO phonetic alphabet version of I, used worldwide.
