Google Play Package Name Checker
Check if an Android package name is available on Google Play Store.
Play Store Checker
Instantly check whether your app package name is still available on Google Play.
Enter a package name to start checking...
Tips:
- Package names usually follow the format
com.company.appname. - Avoid using trademarks unless you own them.
- Once a package name is used on Play Store, it can never be used again, even if the app is deleted.
How to use the Google Play Package Name Checker
Every Android app on Google Play is identified by a unique package name (applicationId) such as com.company.appname. Once an app is published, that name is permanently tied to it and cannot be reused. This tool checks Google Play in real time so you can pick a free name before you start building.
- Type the package name you plan to use, for example com.company.appname.
- Click Check. The tool asks Google Play whether a public listing exists for that name.
- Available means no public app uses the name. Taken means an app already exists; open its listing and choose another name.
- Set the chosen name as applicationId in your app's build.gradle before the first upload to Play Console.
Frequently asked questions
What is an Android package name?
It is the unique ID of an Android app, written in reverse-domain format such as com.company.appname and set as applicationId in Gradle. Google Play uses it as the permanent identifier and in the store URL (play.google.com/store/apps/details?id=…).
Can I change the package name after publishing?
No. A published app on Google Play keeps its package name forever. Using a different name means publishing a new app with its own listing, ratings and installs, so it is worth checking before your first release.
Does "Available" guarantee I can use the name?
Not completely. The tool can only see public listings. A name can still be reserved by an unpublished, removed or suspended app, or by an app that is not visible in every country. Play Console gives the final answer when you upload.
What are the naming rules?
Use at least two segments separated by dots. Each segment must start with a letter and may contain only letters, digits and underscores. Lowercase is recommended, and Google Play does not accept names starting with com.example.
Can I check other app stores too?
Yes. The Global App Presence Checker on CodeBlanks checks the same package name on Google Play, Samsung Galaxy Store, Huawei AppGallery and Amazon Appstore in one go.
