.ba is the Internet country code top-level domain (ccTLD) for Bosnia and Herzegovina. It is administered by the University Teleinformation Center.
The procedure for registering domains within .ba is slightly more complicated than in other ccTLDs; the process is defined by laws and regulations of BiH institutions. For more information, please see Regulations regarding the registration of the BA domain.[2] While international domains can be bought by anyone without any additional requests and documents, .BA domains can be registered by only entities that meet all requirements listed in the Regulations. While domain registration is free, a local presence is needed. Any company that has a registered name or registered trademark in Bosnia–Herzegovina can register an eponymous .BA domain (provided that the domain is not already taken), though some additional caveats apply.
Privately owned second-level domains are permitted, which for-profit companies use. But there are also standardised second level domains:
The rules for the standardised second level domains are fairly well enforced.
