Do Pokémon Card Serial Numbers Change with Grading?

Understanding Pokémon Card Grading and Serial Numbers

In the Pokémon Trading Card Game (TCG) community, grading is a process where cards are evaluated for their condition and assigned a grade by a professional grading service. This grade can affect the card's value significantly. However, it's important to note that the serial number of a card does not change during this process.

Each Pokémon card has a unique identifier, often referred to as a serial number, which is part of the card's design and is printed during the manufacturing process. This number is used to identify the card and does not alter when the card is graded. Grading companies assign their own unique identification number to the graded card, which is separate from the card's original serial number. This grading number is typically displayed on the card holder (slab) but does not replace the original serial number on the card itself.
