"MSB" stands for "Money Services Business". This type of business includes financial services such as money transmission, remittance, prepaid card issuance and virtual currency trading. In the United States, MSBs must comply with a series of federal and state laws and regulatory requirements, and need to obtain appropriate licenses to operate legally.

If you are a money service business (MSB) provider and your app is related to financial services such as money transmission, remittance, virtual currency transactions, etc., then obtaining an MSB license may help your app get listed on the App Store.

Apple's App Store and Google's Google Play Store both have a series of rules and requirements, especially for apps that involve financial transactions. These rules and requirements are generally designed to ensure the security, user privacy, and legal compliance of apps. If the app involves a money service business, obtaining an MSB license can show that the business is legal and complies with relevant regulatory requirements, which can help increase the chances of the app being approved for listing.

However, please note the following:

  1. Although obtaining an MSB license may help your app to be listed on the App Store, it is not the only requirement. You still need to comply with other rules and requirements of the App Store, including user privacy policy, app content, security, etc.

  2. App Store and Google Play Store rules and policies may change over time, so make sure your app remains compliant with the latest requirements.

  3. If your app provides money service business in multiple countries or regions, you may need to consider complying with the financial regulatory requirements of each country and obtaining other licenses or permits if necessary.

Ultimately, in order to successfully list your app, it is recommended to carefully study the rules of the App Store and Google Play Store, ensure that your app complies with all requirements, and work with regulators to obtain the necessary licenses if needed.
