Using Item Numbers in Your Titles

Aug 15, 2025

When buyers shop online or in person through an auction or resale format, they expect clarity and confidence that the item they are viewing, bidding on, or purchasing is exactly what they’ll receive. One of the simplest yet most powerful ways to create this clarity is by consistently adding item numbers to your listing titles.

Why Item Numbers Matter

At first glance, it may seem like a small technical tweak. But for resellers, short item IDs play crucial roles in:

  • Buyer Confidence: When an auction description references multiple photos, having an identifying code makes it easy for buyers to confirm the product in question.

  • Staff Efficiency: Warehouse teams and order fulfillment staff can match sold lots to bins or shelves quickly without double-checking full descriptions or relying only on visuals.

  • Error Reduction: Item mismatches often occur when products are visually similar. IDs prevent confusion between nearly identical models or variations.

Structuring Titles with Item Numbers

Optimal titles strike a balance between descriptive keywords and clear identifiers. Buyers still expect powerful descriptive text for search and SEO, but the short ID should not be hidden. Recommended format:

Example for resale:

Notice how the item number (A102) appears at the very start, quickly separating this listing from any similar iPhone listings on the platform or in an auction catalog.

Best Practices for Assigning IDs

  • Short and Consistent: Keep IDs 3–6 characters long. Overly complex codes waste time and frustrate staff.

  • Sequential When Possible: Sequential IDs (001, 002, 003) simplify cataloging, though category-based prefixes (BOOK100, ELEC201) also work well.

  • Centralized Logging: Maintain one master catalog linking IDs to photos, item details, and storage bins.

  • Avoid Duplicates: Duplicate IDs defeat the purpose. Using a digital log or database prevents overlap.

Linking IDs to Photos and Storage

Adding IDs to titles is only useful when the process is backed with solid cataloging discipline:

  1. Central Catalog: Every new item enters a database or spreadsheet with its assigned ID, details, and corresponding photo links.

  2. Photo Tagging: Rename photo files to include the ID. Example: A102.jpg and A102_detail1.jpg.

  3. Bin/Location Match: Mark bins or shelf spaces with ID ranges to make physical retrieval seamless.

  4. Cross-Check: Before publishing, verify that the ID in the title matches both the photo label and storage location listing.

Tools That Make Item Numbering Easier

While many resellers start with a simple spreadsheet, scaling requires tools purpose-built for cataloging. Gavelbase allows sellers to manage catalog IDs, sync photos, and coordinate storage assignments seamlessly, which is particularly useful for auctioneers or volume resellers. For those not yet ready for a full system, options like Google Sheets paired with cloud photo storage still provide foundational support.

Common Mistakes to Avoid

  • Hiding IDs at the end: If an ID is buried, staff may overlook it. Start titles with the number where it’s most visible.

  • Overly complex formats: SKUs like PRD-ELEC-IPH-128GB-BLK-2025 frustrate buyers. Keep it short.

  • Skipping IDs for low-value items: Low-value does not mean low-risk. Even inexpensive items can cause disputes if misidentified.

  • Not updating reused bins: Clearing and relabeling storage bins must be part of the reselling cycle; otherwise, IDs drift away from actual storage.

Practical Workflow Example

A professional reseller receives a shipment of 50 mixed electronics. Here’s how IDs streamline the process:

  1. Create IDs: Assign E101 through E150.

  2. Catalog Details: Log each item with model, specs, and condition in the central spreadsheet.

  3. Photo Item: Photograph each piece, renaming files accordingly (e.g., E101a, E101b for angles).

  4. Storage Match: Place items into labeled bins, recording bin location under the same ID column in the spreadsheet.

  5. Create Titles: Write listings beginning with the IDs for sales platforms.

  6. Fulfillment: When sold, staff simply matches E101 to its bin and pulls the correct photos for customer order confirmation.

This workflow reduces fulfillment time dramatically while safeguarding against costly shipment errors.

SEO Benefits of Item Numbers

It’s easy to overlook another hidden benefit: search optimization. While search engines won’t rank based on the ID itself, clean and consistent title formats increase click-through rates. Buyers scrolling through dozens of similar products recognize IDs as a marker of professionalism and organization. On auction catalogs especially, keyword-rich descriptions plus item numbers dominate searchability.

Key Takeaways

  • Always begin listing titles with short, consistent item numbers.

  • Back your titles with a central catalog linking IDs to photos and bin locations.

  • Keep formats simple to ensure both buyers and staff can use them effectively.

  • Use supportive tools like Gavelbase or layered solutions with spreadsheets and cloud storage for scalability.

Integrating IDs into both catalog management and listing titles may seem like extra effort, but in resale operations it consistently saves time, reduces disputes, and improves buyer trust.
