What information does 10-88 convey?

• A. Meet Me
• B. On Scene
• C. Switch to Channel
• D. Phone Number

Answer: (D)

The key idea is how information is categorized in these police radio codes. 10-88 is used to indicate a phone number—either that a number is being provided or that a callback should be made. This code specifically communicates contact information in a concise, standardized way, which is why it’s the best match for “Phone Number.” The other options describe actions or statuses (a meeting rendezvous, being on scene, or switching radio channels), which are conveyed by different codes rather than a phone contact.
