Phone Number Barcode Generator
Print phone numbers as scannable linear barcodes for asset tags, shipping labels, warehouse bins and ID cards. Enter one number per line and get a separate Code 128 barcode for each, ready to download.
How Phone Numbers Become Barcodes
Three steps from a list of numbers to printable labels.
List Your Numbers
Type or paste up to 20 phone numbers, one per line, in any format you already have.
Pick How They Are Encoded
Keep them exactly as typed, reduce them to digits, or convert them to E.164. Digits-only produces the shortest barcode.
Size and Export
Set bar width and height to suit your label printer, then download each barcode as PNG or SVG.
Practical Uses for Phone Number Barcodes
When a scanner is faster and more accurate than a keyboard.
A handheld scanner reads a barcode in a fraction of a second with no typos, which matters wherever phone numbers are keyed in repeatedly at a counter or in a warehouse.
- Loyalty and Membership Lookups: Customers who sign up with their phone number can carry a card that the till scans straight into the lookup field.
- Parcel and Courier Labels: Encode the recipient's contact number so drivers can scan it into a delivery app instead of retyping it.
- Equipment Return Tags: Tag laptops, radios and tools with the owner's or department's number for fast identification.
- Event and Visitor Check-In: Print badges whose barcode matches the phone number used at registration.
- Point-of-Sale System Testing: Generate barcodes of fictional numbers to test that scanner input lands correctly in phone fields.
- Emergency Contact Wristbands: Pair a printed number with a barcode so staff can scan it into a contact system quickly.
Code 128 Subsets and Phone Number Length
How the encoding you choose changes barcode width.
| Input | Subset used | Data symbols | Relative width |
|---|---|---|---|
| 12025550147 (digits only) | B for the first digit, then C for pairs | 7 | Shortest |
| 442079460123 (even digit count) | C throughout | 6 | Shortest |
| +12025550147 (E.164) | B for +1, then C for digit pairs | 8 | Short |
| +1 202-555-0147 (as typed) | B with a switch to C for the last 4 digits | 14 | About twice as wide |
| Tel: +1 (202) 555-0147 | B throughout, C for the final 4 digits | 21 | Widest |
Each barcode also contains a start symbol, a checksum symbol and a stop pattern. Code 128-C packs two digits into each symbol, so removing spaces and punctuation roughly halves the width of a phone number barcode.
Linear Barcodes vs QR Codes for Phone Numbers
Pick the symbol that matches the scanner, not just the data.
Code 128 Barcode
1D linear- Read by every standard retail and warehouse scanner
- Types the number into whatever field has focus
- Wide and short, ideal for labels and wristbands
- Holds the number only, with no action attached
- Needs a reasonably flat surface
QR Code
2D matrix- Read by any smartphone camera
- Can trigger a call, SMS or contact save
- Square and compact
- Stores much more data, such as a whole vCard
- Built-in error correction survives some damage
Barcode Printing Best Practices
Settings that keep scan rates high.
Do This for Reliable Scans
- Use digits-only encoding when you can — shorter barcodes fit small labels and scan from further away.
- Keep the quiet zones — the white space on both sides is part of the symbol; do not crop it.
- Match bar width to printer resolution — 2 px bars suit most 203 dpi thermal printers; go wider for inkjet on paper.
- Print black bars on white — red bars are invisible to most laser scanners.
- Show the human-readable text — staff can still type the number if a label gets damaged.
Common Barcode Problems
- Scaling a PNG unevenly — uneven bar widths make the barcode unreadable; use SVG for resizing.
- Printing on glossy or curved surfaces — glare and curvature cause missed scans.
- Using Code 128-C with odd digit counts — it needs pairs; choose Auto to handle this for you.
- Putting personal numbers on public labels — anyone with a scanner or a phone app can read them.
- Encoding non-ASCII characters — accents and emoji are not supported by Code 128-B.

Phone Number Barcode FAQs
Formats, sizes and scanner compatibility.
Code 128, the most widely supported linear barcode for variable-length data. The generator switches between subsets B and C automatically to keep it short.
Yes. Enter up to 20 numbers, one per line, and each gets its own barcode with separate download buttons.
Most scanner apps and many built-in camera apps read Code 128, but it only returns the digits. Use the QR code generator if you want scanning to start a call.
Only if your scanning system expects them. Digits-only is shorter and easier to scan; E.164 keeps the + so the country code is unambiguous.
Subset C can only encode an even number of digits with no symbols. Remove punctuation, add a leading zero, or switch to Auto.
At 2 px per bar, a digits-only 11-digit number is under 300 px wide including margins, which fits common 50 × 25 mm thermal labels.
SVG stays sharp at any size in design and label software. PNG is simpler for printers that only accept images; it is exported at twice the on-screen resolution.
Yes. Code 128 always includes a modulo-103 checksum symbol, which scanners use to reject misreads.
