Fix the address before the label, not after the return
CEP Conferido checks every new order the moment it comes in: does the CEP exist, does it match the city and neighbourhood, is there a street number, is the apartment missing in a building. Problem orders are held and the customer gets a WhatsApp link to confirm or correct the address in one click.
Updated
- CEP looked up in a public CEP database and compared with the street, neighbourhood (bairro), city and state the customer typed.
- Missing street number, a suspicious “s/n”, a missing unit in a building address, and a city-wide CEP with no street or bairro are flagged.
- A phone area code (DDD) that differs from the CEP's region is shown as a warning, so you decide before dispatch.

Customers type the CEP from work with the street from home, forget the apartment number or pick the wrong autocomplete suggestion. Checkout accepts it, the label prints, and the problem only shows up when the parcel comes back or sits with an address exception.
When it comes back, the store pays. The outbound freight is not refunded and, depending on the carrier, the return is charged too. Then come the reship, the support conversation and a customer who blames the store for the delay. In peak weeks such as Black Friday and Christmas, CEP errors rise exactly when the team has the least time to check orders one by one.
Many of these errors are already visible at the moment of the order, if someone looks. CEP Conferido looks at every one, fixes formatting by itself and only asks the customer when the answer depends on them.

With CEP Conferido
- CEP looked up in a public CEP database and compared with the street, neighbourhood (bairro), city and state the customer typed.
- Missing street number, a suspicious “s/n”, a missing unit in a building address, and a city-wide CEP with no street or bairro are flagged.
- A phone area code (DDD) that differs from the CEP's region is shown as a warning, so you decide before dispatch.
- CEP versus address
- City-wide CEP
How it works
- 1
Connect your store
You authorise the connection to Nuvemshop, Shopify, WooCommerce or Loja Integrada, or to Bling if orders flow through it. We go live within 2 business days and agree the hold rules with you.
- 2
Every new order is checked
Within a minute of the order, the CEP is looked up once and compared with the typed address. Formatting fixes, such as the full street name or the state code, are written to the order with the original kept.
- 3
The customer confirms on WhatsApp
Problem orders get an internal hold tag and the customer receives, through your WhatsApp provider or by email, the typed address next to the suggested one to confirm or correct.
- 4
Released or escalated
When the customer confirms, the order updates and is released. If nobody answers within the time you choose, the order goes to your team with the reason noted.
Features
CEP versus address
Compares the street, bairro, city and state of the CEP with what the customer typed. A different city or state holds the order; a different bairro only raises a warning.
City-wide CEP
In towns with a single general CEP, checks that street, number and bairro are filled in, because the CEP alone does not locate the house.
Number and unit
Flags orders with no street number, “s/n” on an urban street, and building or condominium addresses with no apartment, block or house.
Area code and region
Compares the phone's DDD with the DDD of the CEP's region. It is only a warning: many people buy for delivery in another city.
One-click confirmation
A message with the typed and the suggested address, sent through your WhatsApp Business provider or by email. No login for the customer.
Internal hold tags
Uses tags, notes and statuses your platform or Bling already use, so the order is not picked before it is confirmed.
Monthly summary
How many orders were fixed automatically, by the customer or by your team, and which CEPs and bairros caused the most problems.

Compared with the alternatives
- Checking by hand
- Costs nothing, but someone has to open every order, look up the CEP and message the customer before picking. In a promotion week almost nobody manages it.
- Free CEP lookup (ViaCEP, Correios search)
- Great for looking up one CEP at a time and used by many checkouts to fill in the street. They do not compare the CEP with what the customer typed afterwards, do not ask for the number or unit and do not talk to the customer.
- CEP Fácil (Shopify)
- An app listed from US$ 6.99 a month, focused on freight calculation by CEP on the product page. It handles the quote; CEP Conferido handles the address after the order comes in.

Your first week
Every plan starts with a check of your recent orders and a watch-only period before any order is put on hold.
- Day 1: Check of your last 200 orders, with results by email.
- Day 2: Store connected; hold rules and message wording agreed with you.
- Day 3–6: Watch mode: tags only, no holds or messages.
- Day 7: Holds and confirmation messages switched on.
Security and data
- We read only the order fields needed to check the address and send the confirmation link.
- Data is encrypted in transit and at rest; addresses are kept for 90 days for the monthly summary, then deleted.
- Store access uses the platform's own permissions and can be revoked from your admin at any time.
- Messages go out from your number or domain and show only the order number and the address.
- All your data is deleted within 7 days of cancelling, or sooner if you ask.
Questions
Do I need to change my store's checkout?
No. The check happens right after the order, so it works on any Nuvemshop, Shopify, WooCommerce or Loja Integrada plan without editing the theme or checkout.
Does it change addresses without asking?
Only when the change is formatting and there is a single option, such as writing the street name in full or fixing the state code. A different number, unit, bairro or CEP always goes to the customer to confirm.
What if the customer does not reply?
You choose the wait time, for example 12 or 24 hours. After that the order goes to your team with the reason noted, so nothing sits on hold unseen.
Where does the CEP data come from?
From free CEP lookup services such as ViaCEP, with one lookup per order and a cache of CEPs already seen. New CEPs can take time to appear in those databases; in that case the order gets a warning instead of being blocked.
Do I need the WhatsApp Business API?
For the WhatsApp link, yes, through any official provider. Without it, the link goes by email and the order is tagged for your team to contact the customer.
Can I see the results before orders are held?
Yes. Every plan starts with a check of your last 200 orders, showing how many would have been corrected, held or released, and a watch-only period with tags only. Holds and messages start after that. We confirm the plan by email before you pay.
What about LGPD?
We process address and phone data only to check the order and contact the customer about it, as a processor for your store. CEP Conferido is software, not legal advice; confirm your privacy policy with your lawyer.
Let customers fix their own address
From R$ 29 a month, starting with a check of your last 200 orders. No checkout changes.
