Uniden Scanner Serial Numbers

Since the introduction of the BC250D scanner Uniden has used a standardized 11-digit serial number protocol as follows:

• 123456789AB
• 383Z8812345

It is known that the BC780XLT did not use this protocol so it was likely instituted about 2001 with the follow up BC785D and BC250D which did.

The first three characters (in our example "383" indicate the model number, in this example an SDS100.

The fourth character seems to always be a "Z" for scanners, it is possible that this is indicative of the scanner product line.

The fifth character is the year code, in our example is is an "8" so that would indicate a 2018 manufacture date. Depending on the scanner model this could also indicate 2008.

The sixth character is the factory code. These are the known codes used:

• 2 Beta/Engineering
• 4 China
• 6 Philippines
• 8 Vietnam

Characters 7 thru 11 comprise the sequential serial number of the product. In our example the serial number would represent the 12,345th radio of that model type manufactured, assuming that the numbers were applied in the order in which the radio was manufactured.

Missing number series could be used for other product lines like CB and 2-way radios or perhaps internally for projects that may not have made it to a product release.

This is not to be confused with the Electronic Serial Number ("ESN") used on certain Uniden scanners for mode upgrades like DMR, NXDN and ProVoice. This number is similar to the physical serial number but is all numeric (no letters) and 14 characters. For example an SDS200 ESN would be 384260xxxxxxxx. A 3-character alphanumeric "SUM" code follows the ESN with a dash, eg: 384260xxxxxxxx-1A3. The SUM code is used as a check-digit to verify the ESN. HomePatrol units have a dash in the ESN between characters 5 and 6.

The ESN is found by pressing Menu>Settings>See Scanner Information>Firmware Version on most scanners, on HomePatrol units it is obtained by pressing Menu>Advanced Menu>Version Information.

The following domestic and international models were also built during the 2001 to current time frame and likely carry a serial number in this protocol. Please edit them into the list as information is found:

• UBC800XLT (Similar to the BCT15X)
• BC365CRS
• UBC30XLT
• UBC3500XLT
• SC230
• UBC3000XLT (Similar to the BC250D)
