How old is your piano? Where your piano was built? And more ...

OPA - The first and one and only Online Piano Atlas application!
This application tells you the age of your piano - vertical or grand. It will also tell where and when the original factory was established. Often the original factory was closed, and the brand sold. Because of such change sometimes a different company manufactured your piano from a certain time using the same brand name. The Online Piano Atlas also pays attention to these for you. One of the many advantages of our application is that all the data is stored on our online server. This allows real-time user access., and guarantees accurate and up to date information. We can provide or upload new information in seconds, so when your request is posted, the correct and updated answer comes to you instantly.

We separated the upright and grand piano database, since their serial numbers do not necessarily match within the same brand. To start the search, just touch the category icon of your piano. The application will automatically load the appropriate selection of brands.

Our database includes vast number of brands from the past and present sorted alphabetically, and a quick search is also included.These lists are not final, but we are constantly updating and correcting them. If your piano brand is not found, contact us, and we will make all efforts researching and uploading them.

The past decades many piano manufacturers ceased production, and brands changed owners. As an example; a brand manufactured in Germany until 1950 may have been produced in China since 1990. To provide accurate information, in such case we indicate the change, letting you know that your piano was not manufactured in the original factory location or country but in another one.

Often serial numbers also contain letters. For example Yamaha or Kawai serial numbers indicate the country of origin by letters withing the serial number. This is also posted in our application.

If the manufacturer is still in operation, we list the link to their website.

The Online Piano Atlas is available in multiple languages. Currently available languages are: English, German, Hungarian, French and Simplified Chinese. Languages are user selectable.

Nice and convenient.

Great. Checked it against my Pierce Piano Atlas and it checks. Only suggestion is that you add square grands.

Updateded review.
Changed my rating to 3 instead of 4 because now you have to pay. If you added square grands, I would purchase and change my rating.

Really helpful app

I use this app regularly to find out more information about pianos. I am a professional piano technician, and the OPA is very helpful in the field when making decisions about repairs. Thanks to the developer. The only issue I’ve had is when the serial number contains letters, the results often come back as “no such serial number exists...” so if that glitch were worked out it would be even better.

My daily go to.

I use this app almost daily to tell my tuning clients how old their pianos are.
I had an issue with iPhone 11, they jumped right on it and upgraded the app for everybody.
Must have for a professional. The app fee is minuscule and will help fund ongoing research to update the database.
