'ZDNET Recommends': What exactly does it mean?
ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.
When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNET nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.
ZDNET's editorial team writes on behalf of you, our reader. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services. Our editors thoroughly review and fact-check every article to ensure that our content meets the highest standards.

AirTags are a small plastic disk with a built-in U1 chip for Ultra Wideband (UWB) location technology and a replaceable battery. Users attach them to items and keep track of them by using the Find My app from their Apple devices. The great thing about an AirTag is that, not only can it play a sound if it's within range of your iPhone, but you can also see where it is on a map on the Find My app and get directions to it.
Once your iPhone connects to the AirTag nearby, it'll display the distance and direction of it so you can follow the prompts on your screen to be reunited with it.
5. If your AirTag isn't nearby
If you know your AirTag is not within range of your device, as is the case if you put it in a suitcase and are traveling, or if you left an important item behind; then you'll need to find it on the map.
Follow the same steps above, skipping step 4 and instead tapping on the AirTag in your Map, within the Find My app. You can then choose to get Directions to it from your current location.
6. Optional: Play a sound
Once your iPhone is within range of your AirTag, you also have the option of having the AirTag play a sound to make it easier to find.
Just choose your AirTag in the Find My app and tap on Play Sound and you should hear your item.
What is UWB?
Ultra wideband (UWB) is a radio technology that transmits information across a wide bandwidth, using a very low energy level, making it ideal for short-range precise location and tracking in real time.
The iPhone 11 is the first iPhone model to support UWB with its own U1 chip, also included within the AirTag.
Can you track an AirTag with an older iPhone?
If you have an iPhone 10 or older, it doesn't support UWB, but you can still track an AirTag on the map from within the Find My app. Simply follow the steps above to find your AirTag and you should see it in the Maps and have the options to get directions to it.
The technology the AirTag uses is a double-edged sword. Since it has to be near other devices on the Find My network to track it, it's great for tracking through cities and populated areas, especially with as many iPhone users as there are these days. This also means, however, that you can't track an AirTag in rural areas where it isn't within 30 feet of another device or within Bluetooth range of your iPhone.
