Shipping Calculator: Parcel Rates from Houston to Any US ZIP

How the shipping calculator prices a parcel

Parcel shipping from Houston is priced on two things you control — where the box goes and how big and heavy it is — plus a small surcharge on a minority of addresses. Here is exactly how the calculator turns your inputs into a label price.

1. Zone from the destination ZIP. Every ZIP code maps to a shipping zone from 1 to 8 by distance from Houston 77087. The Houston metro is Zone 1; Dallas and San Antonio are Zone 3; Atlanta, Chicago and Miami are Zone 5; Los Angeles is Zone 6; New York is Zone 7; Seattle, Honolulu and Puerto Rico are Zone 8.
2. Billable weight. The label is priced on the higher of the actual weight and the dimensional weight (length × width × height in inches ÷ 166). Under 1 lb is priced by the ounce; from 1 lb the weight rounds up to the next whole pound.
3. One cell on the rate card. The zone and the billable weight pick a single price from the rate card below. That is the label price — there is no fuel surcharge on top.
4. Extras only where they apply. A delivery-area surcharge on some ZIPs ($0.55 or $1.10; $2.75 for remote Hawaii and Puerto Rico addresses), an overweight fee of $16.50 for 20–30 lb parcels and an oversize fee of $16.50 for a box with a side over 23.6 in. Nothing else.
5. Off-network and heavy parcels go USPS. Any ZIP that is not on our regional parcel network, and any parcel over 30 lb or over the network’s size limits, is priced automatically at USPS Ground Advantage commercial rates (up to 70 lb and 130 in length + girth) through our shipping platform — the average USPS rate for that zone and weight, with tracking and $100 of USPS insurance included.

Packaging decides the bill more often than distance does. A 5 lb item in a 14 × 12 × 8 in box is billed at 9 lb because the box’s dimensional weight is 8.1 lb — the same item in a 12 × 10 × 8 in box bills at 6 lb. Enter your dimensions and let the calculator show you the difference before you order cartons.

Delivery times by zone

Transit is counted from carrier pickup at our warehouse. Orders received by 2pm CT, Monday to Saturday, are picked, packed and handed to the carrier the same day, and every label is tracked door to door.

Zone	Where	Typical delivery
Zones 1–2	Houston metro, Gulf Coast Texas, Austin	2–3 days
Zones 3–4	Dallas, San Antonio, Louisiana, Oklahoma, Arkansas, Mississippi, Alabama	4–5 days
Zones 5–6	Florida, Georgia, Carolinas, Midwest, Colorado, Arizona, Mid-Atlantic, most of California	5–6 days
Zones 7–8	New York, New England, Bay Area, Pacific Northwest, Hawaii, Puerto Rico	6–7 days
USPS Ground Advantage	Any ZIP off the regional network; parcels over 30 lb	2–5 business days

What the label price includes, and the only extras

Included in every label

• Door-to-door tracking with a public tracking link for your customer.
• Up to three delivery attempts before a parcel is returned.
• No fuel surcharge and no residential surcharge — the card has neither.
• Pickup from our Houston warehouse, same day for orders in by 2pm CT.
• USPS Ground Advantage labels (off-network ZIPs, heavy parcels) include tracking and $100 of USPS insurance.

Extras, charged only when they apply

Priced on USPS Ground Advantage instead of the network

• Parcels over 30 lb billable weight (USPS takes them to 70 lb), a longest side over 35.4 in, or length + width + height over 59.1 in (USPS allows 130 in of length + girth) — the calculator switches automatically. Beyond the USPS limits it is freight, quoted in writing.
• ZIP codes outside the regional network, including all of Alaska, North Dakota, South Dakota, Vermont and West Virginia.
• PO Box and APO/FPO/DPO addresses — always routed to USPS at fulfillment, whatever the ZIP.

What you can ship, and how to pack it

Most ecommerce goods ship without a second thought: apparel, accessories, supplements in sealed retail packaging, beauty products without alcohol-based sprays, books, toys, electronics with installed batteries, home goods and pet supplies. Pack to survive a parcel network — a rigid box or padded mailer with the item unable to shift — because damage traced to packaging is not claimable.

Prohibited: alcohol, tobacco and vape products, medicines and medical devices, perishable or temperature-controlled food, live animals and plants, cash and high-value goods (jewelry, precious metals, artwork), firearms parts and replicas, and regulated hazardous materials including standalone lithium batteries.

Restricted (pre-approval and compliant packaging required): perfume and other alcohol-based cosmetics, aerosols, nail polish, household chemicals, shelf-stable packaged food, magnets and knives. Tell us what you sell before your first inbound and we confirm the right service for each SKU.
