Hey Vickie4231,
We'd recommend reviewing this article as it provides steps to help resolve issues with AirTags not showing on the map: Find your keys, backpack, and more with AirTag - Apple Support
"If you don't see your AirTag in Find My
- Remove and then reinsert the battery of your AirTag.2
- If your AirTag doesn't play a sound after you reinsert the battery, replace the battery with a new CR2032 battery.
1. Your AirTag must be within Bluetooth range to use Find Nearby or play a sound using your iPhone, iPad, or iPod touch. If it's out of range, get directions to it first. Find Nearby uses Ultra Wideband, which is not available in all countries or regions. Learn more about Ultra Wideband availability.
2. Warning: AirTag, the battery cover, and the battery might present a choking hazard or cause other injury to small children. Keep these items away from small children.
The Find My network isn't supported in South Korea and might be unavailable in other regions due to local laws. "
Thanks!
