No two transfer boxs are quite the same across different vehicles, so getting the specifics right matters when you buy used, second hand or a replacement. Answer a few quick questions below and breakers will only quote if they have the exact matching part in stock:
No — the B-Class is a front-wheel-drive only model across all generations and was never offered with four-wheel drive or all-wheel drive in standard production, so it was never fitted with a transfer box. A transfer box is only found on vehicles that send drive to more than one axle, which the B-Class does not do. If your B-Class has a drivetrain problem, you are most likely looking for a gearbox (automatic or manual), a differential, or a driveshaft rather than a transfer box.
That is almost certainly a misdiagnosis or a misunderstanding of the part name — neither the first-generation W245 B-Class (2005–2011) nor the second-generation W246 B-Class (2011–2018) was built with four-wheel drive, so neither generation ever had a transfer box fitted. The part your vehicle actually needs is most likely the automatic or manual gearbox itself, or possibly a driveshaft, CV joint, or differential component. Describe your symptoms to a breaker and give them your registration so they can identify the correct part.
Mercedes-Benz did not offer a 4MATIC (four-wheel-drive) version of the B-Class, so there is no 4MATIC variant that would carry a transfer box. You may be thinking of other Mercedes models such as the GLA, GLC, or C-Class that are available with 4MATIC and do have a transfer box — if you own one of those, a breaker can help you source the correct unit. Double-check your model on your V5 logbook, as the B-Class and GLA can look similar.
Depending on the fault, the parts most commonly needed on a B-Class drivetrain are the gearbox (either a 6-speed manual or a 7G-DCT dual-clutch automatic depending on your engine and year), a front driveshaft, a CV joint, or a differential built into the gearbox casing. When contacting a breaker, give them your registration number and engine code — found on your V5 or via a VIN check — as fitment of these parts is closely tied to your specific engine code rather than just the model year or trim level. A breaker can then quote you accurately for the correct unit.
