Fast Set inflatable-ring pools
- Look for
- Serial, item/product number and production-date marking.
- Label location
- On the outside of the liner beside the drain valve.
Do not use the removable pump serial to identify the pool liner.
Read the plate. Check the evidence.

What’s on the rating plate?
Bestway products carrying a separately identified YYYY-MM-DD production-date stamp; certain filter, pool-heater and spa-pump support pages use this date as the serial number.

Read the label on your product
Where to find the numbers.
A pool liner, pump, cover and accessory can each have their own identifiers. Find the marking on the component you are identifying. The manufacturer illustrates YYYY-MM-DD and DDMYY date fields; only the full YYYY-MM-DD field has a verified interpretation here.
Steel Pro, Steel Pro MAX and Power Steel frame pools
- Look for
- Serial, product/item number and production date.
- Label location
- At the pool drain-valve area on the liner.
Bestway USA also places the liner SKU underneath the serial near the drain valve. Kit SKU and liner SKU can differ.
Hydrium steel-wall pools
- Look for
- Liner serial and product/item marking.
- Label location
- Printed on the inside pool liner approximately 15–30 cm below the top edge.
The mosaic pattern can make the printing hard to see. Look carefully against the mosaic print.
Lay-Z-Spa / SaluSpa inflatable liners
- Look for
- SERIAL#, item/product number and YYYY-MM-DD or DDMYY date.
- Label location
- Check the illustrated label by the upper inside wall or near the inflation-valve area; some rigid/inflatable designs put a second marking outside near the lower wall.
Placement varies by liner style. Read liner, cover and pump separately.
AirJet / HydroJet spa pump units
- Look for
- Item number and YYYY-MM-DD date-as-serial; later diagrams also show separate component serial/date markings.
- Label location
- On the pump housing; some units stamp the date near the lower handle/base and put the item label on the side.
Different pump housings use different positions. Do not infer a whole-spa model from the pump date.
UltraFit spa pump/control units
- Look for
- Item number, separate serial where present and production date.
- Label location
- On the unit housing; compare the manufacturer diagram for the fitted pump style.
Do not open the electrical casing to look for the external marking.
Flowclear cartridge-filter pumps
- Look for
- Item/model or P-prefixed component number; separately stamped YYYY-MM-DD or DDMYY date.
- Label location
- On the lower side of the pump casing or base; the product label may be higher on the housing.
Some newer designs show DDMYY only; that compact code is not decoded here.
Surface skimmers / wall-mounted filter units
- Look for
- Product/item marking and separate production-date stamp.
- Label location
- On the outside of the motor/filter housing, with a separate product marking toward the lower casing.
Verify whether you are reading the skimmer motor or another pool component.
Flowclear sand-filter systems
- Look for
- Separate item/model label and YYYY-MM-DD date-as-serial; newer guide also shows DDMYY.
- Label location
- Product label on the silver rating plate or base; date-as-serial on the pump base, motor support or filter-tank lower foot, depending on the pictured assembly.
Tank, motor/pump and base can have separate markings.
Electric pool heaters
- Look for
- YYYY-MM-DD production date used as the serial.
- Label location
- Below the power-cable entry on the outside of the device.
The embossed stamp can be faint. Inspect with the unit switched off and disconnected.
Pool heat pumps
- Look for
- Production date used as serial plus separate product label.
- Label location
- On the exterior appliance body; compare the side/base area with the official diagram.
Exact position depends on housing; no factory or refrigerant details are inferred.
Pool-cleaning robots
- Look for
- Item/product or component label and production-date stamp; exact layout varies by model.
- Label location
- On the underside of the robot.
Switch off and remove safely from the water before inspecting.
Electric air pumps / inflation pumps
- Look for
- Product/item label and YYYY-MM-DD or DDMYY stamp.
- Label location
- On the outside housing or underside/base, depending on the pump shape.
The pump date identifies the pump component only.
Solar / outdoor pool showers
- Look for
- YYYY-MM-DD or DDMYY production-date marking.
- Label location
- On the lower column near the base and hose connection, as illustrated.
The guide does not publish a unique-serial-to-model formula.
Hydro-Force stand-up paddle boards
- Look for
- A-prefixed identifier with separate DDMYY or YYYY-MM-DD date.
- Label location
- On the underside toward the tail, near the fin fitting.
Do not treat the A prefix as a factory/date code. Country and individual manufacturing plant are unverified.
Bestway trampolines
- Look for
- Product/serial marking and DDMYY stamp.
- Label location
- On an outer frame/leg area near the lower rim, as illustrated.
The compact DDMYY format remains guidance-only.
Airbeds with built-in pumps (historic guide)
- Look for
- YYYY-MM-DD production-date stamp.
- Label location
- On the exterior built-in pump panel/body, as shown for several airbed styles.
This dates the pump or marked airbed component; current designs may differ.
Electric trolling / outboard motors (historic guide)
- Look for
- Production-date stamp and separate product identifier.
- Label location
- On the motor housing near the mounting bracket; the separate product mark may be elsewhere on the housing.
Do not infer boat manufacture date from a separately supplied motor.
Scope matters
Supported formats
and historical limits.
- This is a production-date reader, not a universal decoder of the separate SERIAL#, BW, CN or A-prefixed identifier. Those serial digits do not have a verified public date or exact-model formula here.
- The current manufacturer guide also prints the format DDMYY. It does not explain the month symbol, provide a month alphabet or show a real example. This compact code is identified but intentionally not assigned a date.
- The five-character item/model number (which can contain letters), a P-prefixed component number, the complete pool/spa serial and the production date are different fields. Do not enter an item number as a compact date.
- A pump, liner, cover and other component may each have their own date and serial; a replacement component date does not date the whole kit.
- No country, factory, quantity, warranty status or exact model is inferred from a date. Use the separate item/model marking for the linked manuals search.
- Bestway manufacturer lookup can identify some pool and spa serials, but this tool does not query it or claim to contain that private serial-to-product database.

Bestway labelled YYYY-MM-DD production date
Only the YYYY-MM-DD production-date field identified in Bestway diagrams, including documented date-as-serial heater, sand-filter and spa-pump markings. Dashless transcription is accepted.
YYYY is the full year, MM is the calendar month and DD is the day. The result dates the component bearing the stamp. The separate unique serial and product/item number are not decoded. DDMYY is not supported because its month symbol is unexplained in the sources.
Confirm that this is the YYYY-MM-DD production-date stamp on your Bestway product, or the date-as-serial marking described for your filter, heater or spa pump. Select this system only for that field; a separate eight-digit serial or item code is insufficient.
Reading your result
Bestway lookup questions
Why does the year code match more than one year?
Some systems reuse letters or only encode the last one or two year digits. Every supported interpretation is retained. A decade supplied from reliable records can narrow the reading; the tool does not automatically pick the newest year.
Does the serial identify my exact model?
Usually the model is a separate plate field. Where published serial ranges actually identify a model, the result shows model candidates and links to their manuals. Overlapping ranges remain ambiguous.
Can I share the result?
After a lookup, the address includes the serial in a fragment beginning with #serial=. Use “Copy share link” to share the serial and selected context. Opening the link runs the same lookup. The fragment is not a query-string result page.
