You won’t have any trouble differentiating between 15 and 20A GFCIs because they don’t have the same design. Just like ordinary outlets, 15 and 20A GFCIs have three slots. They are designed to accommodate 3-prong plugs. 20A outlet has a T-shaped prong.
What is the differnet between 15 amp and 20 amp?
A 15-amp circuit is typically serviced by 14-gauge wire and safeguarded by a circuit breaker or fuse. A 20-amp circuit must be serviced by 12-gauge or 10-gauge wire and protected by a 20-amp breaker or fuse. Circuit breakers are designed to open the faulty circuit automatically before any further damage can be done.
What is difference between 15 vs 20 amp receptacle?
A 20a receptacle will have one slot that is turned sideways or T shaped to allow a 20amp plug to be used. A 15amp receptacle on a 20 amp circuit will not overload the circuit. You will only be allowed to plug in 15a devices.
Does a microwave need a 15 or 20 amp circuit?
The short answer to this question is yes! most countertop microwave oven do need a dedicated circuited i.e commonly a 15 amp or a 20 amp dedicated branch circuit.

Making statements based on opinion; back them up with references or personal experience.
Can you use 15A receptacles on 20A?
That dances together with the Electrical Code, which allows 15A receptacles plural to be used on 20A circuits, as is the case you will often find in kitchens and bathrooms. By making GFCIs 20A internally but 15A on their face, it allows you to use the same GFCI on both 15A and 20A circuits.
What is the Difference Between 15 Amp and 20-Amp GFCIs?
15 amp and 20-amp GFCIs are not the same. They have various differences that affect the work they do, for instance:
Can I Use 20-Amp GFCI On 15 Amp Circuit?
You can’t use 20A GFCI on a 15A circuit because a 20A GFCI will draw more power than the 15A circuit can handle. This will cause the breaker to trip. If the breaker malfunctions, you could start a fire, especially if you are using that 20A GFCI to operate a 20A appliance.
