Yes. Use "Add Another Box" on the shipping form to add multiple packages. Enter dimensions and weight for each. You'll get one combined rate and one label set for the whole shipment.

Each package must be within 22" × 18" × 15" and under 50 lbs.

After payment, use "Open Label PDF" on the order complete page or "View label" in your Dashboard. Open the PDF and print at 4×6 or letter size. You can also show the label on your phone at a carrier drop-off.

Use the carrier shown on your label (USPS, FedEx, UPS, etc.). Drop off at any location that accepts that carrier — retail stores, lockers, or post offices.

It's an optional field to add your PO number, order number, RMA, or any internal reference. It will appear on your invoice and dashboard for easy searching.

SynapseShip is for simple domestic parcels: everyday retail goods, clothing, books, small electronics (when allowed by carrier rules), returns, gifts, and similar items that do not require special permits, hazmat paperwork, or extra carrier documentation beyond printing your label.

Do not ship hazardous materials (including many flammable, corrosive, or toxic substances), chemicals such as strong acids, solvents, or poisons, explosives or ammunition, radioactive materials, biohazards or medical waste, marijuana or other federally illegal substances, human remains, live animals, perishable food that needs refrigeration, unstabilized lithium batteries shipped outside normal retail rules, cash, bearer instruments, or precious metals sent as negotiable value. When in doubt, check the carrier’s prohibited list or contact support before purchasing a label.

Carriers apply strict rules to lithium batteries, aerosols, perfumes, alcohol, and many regulated products. Our checkout assumes standard retail parcels without ORM-D markings, dry ice, adult signature requirements, export licenses, or similar add-ons. If your shipment needs hazmat labels, special licenses, or customs documentation, it is not a fit for our self-service flow — use a carrier retail location or a licensed freight specialist.

No. The platform is focused on straightforward U.S. domestic shipping without extra paperwork. International shipments, customs forms, and commodity filings are outside what we support today.

When you're logged in, you can save sender and receiver addresses. Type a name in the receiver field to see saved addresses and auto-fill the form. Manage all addresses under Dashboard → Address Book.

We use Google Places to auto-suggest addresses as you type. Select a suggestion and the street, city, state, and ZIP fill automatically — reducing errors and speeding up the process.

The address could not be verified. We'll tell you which address (Ship From or Deliver To) has the issue and suggest corrections. You can fix it or proceed anyway if you're confident.

Use the Track page (accessible from the header), enter your tracking number, and see real-time status updates including estimated delivery date.

Carriers often take 24–48 hours to show the first scan. If the package is lost, file a claim with the carrier. We can provide proof of purchase if needed.

Yes — when the carrier marks your package as "Delivered," you'll receive an email notification if you have tracking emails enabled in your profile settings.

Didn't use your label? No problem. Open your Dashboard, expand the shipment details, and click "Request Void/Refund." Processing typically takes a few business days.

Refunds are not available if: (1) the carrier has already scanned the label, or (2) more than 30 days have passed since label creation. These are carrier-imposed rules.

Absolutely. We use Stripe for payment processing — your card details never touch our servers. Stripe is PCI-DSS Level 1 certified, the highest level of security in the payments industry.

Labels usually appear within a minute. Check your email or log in and check your Dashboard under "My Shipments." If it's still missing after a few minutes, contact us with your payment email or order reference.
