# How to input prefixes to SKU in Update Feed?

Question:

I have to make some changes to the feeds since my current company has added vendor designations before the SKU, i.e. for Apollo, they have A-SKU. But the feeds do **NOT** have that designation before the SKU. They have a program that automatically looks within that vendor's files and then adds the inventory and images. Let me know how you can handle that issue.

### Store Prefix/Postfix

When the SKU in the store has more character than the SKU in the feed.

For example: 
SKU in store = ABC1234 
SKU in feed = 1234 Insert ABC as the store prefix

  
### Feed Prefix/Postfix

When the SKU in the feed has more character than the SKU in store. The prefix/postfix will help you to match the extra character from the SKU in the feed.

For Example: 

SKU in store = 1234 
SKU in feed = XYZ1234END 
Feed prefix = XYZ 
Feed postfix = END
 
### Does it handle support prefixes?

Yes, the handle does support the prefixes. For Example:

Feed:[https://www.helloshop26.fr/products/meuble-tele-buffet-tv-television-design-pratique-2-pcs-agglomere-120-cm-chene-et-blanc-brillant-2502081](https://www.helloshop26.fr/products/meuble-tele-buffet-tv-television-design-pratique-2-pcs-agglomere-120-cm-chene-et-blanc-brillant-2502081)

**Store**: meuble tele buffet tv television design pratique 2 pcs agglomere 120 cm chene et blanc brilliant 2502081/2
 
**Prefix that can be used**: HTTPS://WWW.HELLOSHOP26.FR/PRODUCTS/


### Where to add a prefix in your feed setup

To add a prefix during feed setup, go to **Step 2: Matching column**, select the SKU column, and open the **Smart Setting** options. There you can enter the prefix or postfix you want to apply.

### Removing unwanted prefixes
If the feed contains an unwanted prefix (for example an apostrophe `'` before the SKU), removing it in the **Smart Settings** ensures the SKU matches the store SKU correctly and prevents updates from showing 0 updated.
