🔐 Serial Decoder

Decode any serial number.
Get the manufacture date in milliseconds.

Each manufacturer encodes the production date differently. We've built deterministic, brand-specific decoders for every major brand — Samsung's position-8 letter, Whirlpool's month rotation, GE's H=May encoding. No guessing.

Brand coverage

Every major brand.
Brand-specific logic.

Generic serial parsers guess. We decode. Each brand gets its own deterministic logic built from official spec sheets — not pattern matching.

Samsung

Position 8 letter → year · month

0H9E4ABTA → H=2021, 9=May

Whirlpool

Letter rotation (month) + 2-digit year

CS4138XYQ0 → C=March, 19xx

GE Appliances

Position 2 letter = month + position 3-4 = year

HL180392G → H=May, L=2018

Year digit + month letter at positions 1–2

903KWPG → 9=2019, 03=March

Frigidaire

Letter + 2-digit year + week number

XA4312345 → 2004, week 31

How it works

Deterministic decoders,
not AI guesses.

📋

Brand-specific encoding tables

We build a decoder for each manufacturer's serial format from official spec sheets and verified production data — not reverse-engineered guesses.

🔬

AST-sandboxed Python decoders

Each decoder runs in an isolated sandbox. New brand decoders are generated by AI, then validated against known serials before going live.

📊

Confidence scoring

Every decode returns a confidence score — HIGH, MEDIUM, or LOW. If we can't decode a serial, we return null rather than fabricate a date.

🔄

Automatic learning

When our AI cracks a new brand's serial format through pattern analysis, it's tested, validated, and added to the decoder library automatically.

⚡

Millisecond decode

Serial decoding is deterministic — not an LLM call. Once the decoder exists, it runs in <1ms. Latency comes from the rest of the lookup pipeline.

🌐

International format support

Handles serials from US, Canadian, European, and Asian manufacturing plants — including multi-factory brands like Samsung and LG.
