Borderlands 4 Item Serial Codes

Browse 112 Borderlands 4 item serial builds covering 20 named item designs, copy a complete code, and use it in the BL4 save editor. The directory organizes items by their available type, rarity and manufacturer information so you can find equipment without searching through a long text dump.

The directory includes legendary Jakobs pistols, Torgue shotguns, Ripper SMGs and Torgue shields. Numbered weapon builds distinguish different scope and grip combinations of the same item. Shield labels show the item level.

A serial describes the item, including its encoded level and parts. It does not contain your whole character, account ID or saved mission progress. Keep the original save when editing a collection, and retain the old serial if you want to recreate an individual item later.

BL4 codes commonly begin @Ug and include punctuation because they use Base85 text. Copy every character exactly. BL2 codes beginning BL2( and BL3 codes beginning BL3( belong to other games and use different formats. Use the BL4 serial decoder to inspect the text representation before preparing an equipment change.

How to use these codes

Find an item with the search and filters, then copy its complete serial. For several codes, add the builds you want to the selection and choose Add to BL4 editor. The selected serials travel with the list; your save and account ID remain in the editor's local session.

Import a numbered character file with its owning Steam ID or Epic Account ID, then use Add items to put the codes into the backpack. Import profile.sav when adding them to the shared bank. Review the new entries and apply the change before downloading.

You can also change item levels or delete existing entries from Inventory. Keep the original codes and file backup when changing a collection. Download the edited save, close the game and replace the matching file under its original filename. The save-editing tutorial covers cloud synchronization and restoration.

How BL4 serial codes work

Base85 converts the item's binary data into a compact text string. Its punctuation is part of the code, so do not trim characters from the middle or convert it into another game's item-code prefix.

The serial decoder reads an item's level, manufacturer and parts, changes its level or an existing part, and encodes the result. It also converts Base85 into readable BL4-TOKENS/1 text and back. Use Base85 when importing a code into the save editor or another tool that accepts BL4 serials. Keep a copy of the original code before editing.

Can I use these codes in Borderlands 2 or Borderlands 3?
