Fidelity Error (004983) The symbol you entered, BRK/B is not recognized

Someone asks:

What’s the deal? I can’t look for Berkshire Hathaway shares on Fidelity.

(004983) The symbol you entered, BRK/B is not recognized. BRKB may be the symbol you are looking to trade. Please verify the symbol and re-enter your order.

Answers:

Mike K:

Don’t use the / when using the app to trade. Remove the /. Just use BRKB.

Peter P:

Just search for BRK and then select the B stock from the dropdown. Basically whatever the system uses to designate the share classes displays as “/“, but that’s not what’s actually being used.
