# Can we add a prefix or postfix during the add process?

Yes, it is possible. You should use the [custom format](https://help.stock-sync.com/en/article/custom-text-formatting-in-description-vendor-title-sku-fields-1m4fjwl/?bust=1732769730527) method under the SKU field.

Alternatively, you can also add a prefix directly from **Step 2: Matching Column** by selecting the SKU column and using the **Smart Setting** prefix option. 

| Example:
| To add "ABC" as a prefix in front of your SKU, "1234" from the feed file, you should map the field as ABC{{SKU}}

| Another Example:
