Free tools for wholesale electronics traders
Small, fast, browser-only utilities for the verification and operational steps wholesale buyers and sellers run on every deal. No login, no upload, no data leaves your browser.
IMEI Check
Validate a single IMEI in your browser. 15-digit format check, Luhn checksum, and TAC region lookup. Useful for a one-off spot-check before responding to a counter-offer.
Bulk IMEI Checker
Paste up to 100 IMEIs and get a per-row format + Luhn verification. Catches Excel mangling, fabricated numbers, and obvious manifest errors before you ever pay for a paid GSMA lookup.
GSMA Status Decoder
Plain-English decoder for the 12 most common GSMA blacklist status flags (clean, lost, stolen, unpaid, fraud, in-finance, and the rest). What each one means for resale risk, with the action you take next.
iPhone Part Number Decoder
Paste a part number like MG913LL/A. The first letter reveals new, refurbished, replacement or personalized (M/F/N/P); the suffix reveals the sales region. Catches refurb units hidden in a lot before you buy.
Wholesale Offer Formatter
Turn your stock details into a clean, copy-ready WTB or WTS offer with every field buyers expect. Free, runs in your browser.
Wholesale Margin Calculator
Blend a mixed Grade A/B/C lot into one margin. Enter unit cost, lot size, the grade split and resale prices, fees and shipping; get per-unit profit, lot margin, markup and breakeven.
Landed Cost Calculator
True per-unit cost of an imported phone lot. Enter goods, freight, insurance, plus your own duty and VAT/GST rates; get duty, tax, landed total and cost per unit. No bundled rates, you supply them.
Phone Receiving Checklist
A 23-step CSV workbook for incoming count, IMEI matching, functional sampling, grade verification, evidence, and claims. Assign owners and keep the completed file with the shipment record.
How traders use these
Three minute-long checks that catch the cheapest mistakes in a wholesale lot before money moves.
Spot-check a single IMEI
A buyer drops a sample IMEI in chat. Paste it into IMEI Check before you reply: 15-digit format, Luhn checksum, TAC region. Two seconds of work.
Validate the full manifest
Once a counterparty shares the lot CSV, run the whole list through Bulk IMEI Checker. Anything that fails format or Luhn is a manifest error to fix before you pay for a paid GSMA lookup.
Decode the GSMA flag
When a paid IMEI service returns a status code, the GSMA Status Decoder tells you what each flag means for resale and what the recommended action is.
What these tools don't do
They run mechanical checks: format, Luhn checksum, TAC lookup, GSMA-flag interpretation. They do not query the live GSMA blacklist, iCloud Activation Lock, MDM enrollment, or carrier-lock status, because those require server-side database access and a paid service. For the full pre-payment workflow including the paid lookups, read IMEI checks for wholesale bulk phone buyers.
On the roadmap
More tools are next. If you would use one, write to connect@aikon.app and we will prioritise accordingly.
- TAC to model lookup Paste a TAC or full IMEI and get the manufacturer and model it encodes, in single and bulk modes, from a bundled device database.
- iPhone A-number decoder Paste an A-model number like A2342 and get the model, market region, and the variant and band watch-outs that affect cross-region resale.
- Battery-grade estimator Enter battery health and a few cosmetic answers and get a suggested A/B/C grade, using the public grading thresholds from our grading guide.
