Equivalent pills — same medicine, different imprint

The pills below contain the same active ingredient at the same strength (Lithium Carbonate 300 mg). Different makers stamp their own codes, so equivalent pills often look completely different. This is factual label information — it is not a suggestion to substitute one product for another; only a pharmacist or prescriber can advise on that.

How can I be sure this identification is right?
