Container number check (ISO 6346)

2026-10-12T22:59:31-06:00

Every shipping container carries an eleven-character identity under ISO 6346: four letters and seven digits. The final digit is not arbitrary. It is a check digit, calculated from the preceding ten characters through a modulo-11 algorithm with positional weighting. Enter a container number and this tool will tell you whether that check digit is consistent — valid or invalid.

Container number check

A working tool — and a small illustration of what compliance really means.

Why this matters for an Authorised Economic Operator

A single invalid check digit is usually just a typing error. But a pattern of them, running through a cargo administration, is something an auditor reads differently. It signals that container numbers are being entered without verification — and a registration that isn't verified at the point of entry is a registration that cannot be fully trusted downstream. In OEA terms, this touches directly on process security and the integrity of transport-unit records — the domains a customs authority examines most closely. If the recorded identity of a unit cannot be relied upon, neither can the traceability that depends on it.

That is the difference between knowing that a check exists and understanding what its absence reveals. A container that arrives with a number that does not validate, or a seal number that does not match the one recorded at departure, is not a clerical curiosity — it is a question that a well-run operation should already have answered before the authority asks it.

Who holds OEA status

2026-10-12T22:58:31-06:00

Twenty-nine operators on the DGA's published register, in three activity classes. Public: the name and the activity. Not public: the certificate's content.

Is this company an OEA?

Check the Directorate-General of Customs' published register.

✓ Whether the company is on the DGA's published list, and its certified activity type.
✕ The content of its individual certification — which facilitation measures it holds. That is not public.
✕ Whether the certificate is currently suspended. Suspension status is not published in real time.

The register is dominated by medical/pharma and tech multinationals — the operators with volume and internal-control maturity to carry the investment. For a mid-sized importer, the useful question isn't "am I like them?" but "what would it take to get there?"

The guarantee question, answered properly

2026-10-12T22:57:31-06:00

A question that comes up often: do OEAs post security for missing goods? The honest answer needs two things the law keeps apart.

1 · Guarantee on the customs debt

What auxiliary operators must post as a garantía global:

Operator	Amount (CA-peso)	Article
Customs agent	20,000	34
Transporter (transit)	50,000	41(c)
Depositary	150,000	47(e)

CA-peso = peso centroamericano, a regional accounting unit pegged 1:1 to the US dollar — not a circulating currency. Costa Rican customs law states these amounts in CA-pesos "or the equivalent in national currency" (colones), converted at the prevailing rate when the guarantee is posted. So 20,000 CA-pesos ≈ USD 20,000, payable in colones at the day's exchange rate.

2 · Liability for missing goods

A separate basis. Anyone receiving, handling or holding goods under customs control is liable for the fiscal consequences of damage, loss or theft (art. 26). A depositary answers for goods declared-received-but-not-found (art. 48c). Loss by force majeure extinguishes the debt proportionally (art. 64).

The OEA twist

An importer or exporter with OEA status is not an auxiliary operator. Abbott, Philips, Café Britt are OEAs as importers/exporters — they don't post the agent, transporter or depositary guarantees, and their benefit is the reverse of posting security: deferred payment without a guarantee (art. 267.1).

So for importer/exporter OEAs, pre-posted security for missing goods is not a certification requirement. The underlying liability (art. 26/64) still exists — it just isn't covered by a lodged bond. For the cargo-terminal OEAs — Rex, Santamaría, TICAL, UPS — the depositary logic does apply, and whether OEA status softens the 150,000-peso requirement is set by Regulation 44051-H, not the statute.

The nine facilitation measures

2026-10-12T22:56:31-06:00

The DGA may grant any of nine benefits, according to the operator's activity. Those two words matter: a certificate grants a specific subset — not all nine automatically, and two OEAs are never equal.

1Deferred payment without a guarantee — and without the 20%-of-prior-year bond art. 61 bis otherwise requires.
2Accumulated declaration with no minimum monthly-import threshold.
3Expedited clearance procedure.
4Priority in the application of customs controls.
5Personalised, priority handling of procedures.
6Priority during disruptions — threats, port or border closures.
7Inspection at your own premises, where applicable.
8International recognition through Mutual Recognition Agreements.
9Other benefits the DGA sets by general resolution.

These measures cannot be transferred or granted to third parties. Which subset an operator receives is written into its individual certification — which is not public.

The requirements aren't in the statute

2026-10-12T22:55:31-06:00

A frequent misconception is that the law tells you how to get certified. It doesn't. The statute frames the programme; the operative requirements sit in a structured body of DGA resolutions, security policies, procedures and self-assessment questionnaires — updated regularly, differentiated by tier and by operator type, and cross-referencing one another.

Certification succeeds or fails on how accurately your operation is mapped against that body of documents — the right security policy, the right questionnaire for your activity and tier, the current version of each. This is where most applications stall: not on eligibility, but on navigating the documentation correctly and keeping it current across the four-year cycle.

Knowing which documents govern your case, in their current form, and how they fit together, is the substance of the work.

An MRA doesn't make the requirements the same

2026-10-12T22:54:31-06:00

A common assumption is that mutual recognition means an EU AEO automatically satisfies Costa Rica's OEA requirements, or the reverse. It does not — and that gap is exactly where the practical problems sit.

What an MRA actually does

Recognition grants benefits at the border and removes duplicate verification: an operator accepted as an OEA by one participating customs service isn't re-vetted by the others. It does not harmonise the admission requirements. The two programmes stay distinct; each side keeps its own rules.

Where the friction is real

Different validation basis. MRAs are signed only after mutual compatibility studies — proof the programmes are not identical. Costa Rica and China ran such studies from 2019 before signing.
Converging classes, not identical. Since early 2025 Costa Rica grants two tiers: OEA Simplificaciones and OEA Simplificaciones Aduaneras y Seguridad — close to the EU's AEOC/AEOS split. Closer than before, but the security requirements and self-assessment questionnaires are Costa Rica's own, so an EU tier still doesn't map automatically onto a CR tier.
Different obligations. Four-year validity with mandatory re-application versus the EU's indefinite, monitored status; the article 268 self-assessment cycle; a distinct guarantee architecture.

The point that matters for a multinational

A company holding EU AEO status that wants OEA certification in Costa Rica cannot lean on its European certificate. It runs the Costa Rican procedure separately, and the internal-controls documentation the EU accepted must be re-mapped to what Regulation 44051-H requires. Given that the current OEA register is almost entirely multinationals — most of whom hold EU or US AEO-equivalents — this is not hypothetical. It's the usual starting point.

Who recognises a Costa Rican OEA

2026-10-12T22:53:31-06:00

Article 266 recognises as an OEA any operator certified and active in the AEO programme of a country with which Costa Rica holds a valid Mutual Recognition Agreement (MRA). Recognition runs both ways — a Costa Rican OEA is granted benefits at the partner's border, and vice versa. Costa Rica's MRAs fall into four groups.

Central America

Panama · Guatemala · El Salvador · Honduras. The regional customs-union neighbours.

Bilateral

Mexico (SAT–DGA) · Colombia · China (signed April 2023 — preferential clearance, access to 4,500+ certified Chinese operators).

Regional Agreement of the Americas

Argentina · Bolivia · Brazil · Chile · Colombia · Guatemala · Paraguay · Peru · Dominican Republic · Uruguay. The largest OEA MRA signed to date.

Not the US, not the EU

No operational OEA MRA exists with either — Costa Rica's two largest trading partners. The EU–Central America Association Agreement (in force May 2024) is a trade agreement, not an AEO MRA. A Costa Rican OEA gets no automatic recognition in Brussels or Washington.

Roughly 15–16 countries in total — nearly all of Latin America, plus China. Verified against the DGA's published materials to 2026: unchanged since the China arrangement of 2023. Note that Costa Rica's trade agreements with Ecuador (2024) and the UAE (2025) are free-trade agreements, not OEA MRAs.

Recognition does not mean the requirements are the same. See An MRA doesn't make the requirements the same.

What OEA is — and how Costa Rica's version differs

2026-10-12T22:52:31-06:00

In Costa Rica the AEO programme is called OEA, Operador Económico Autorizado. Both derive from the World Customs Organization's SAFE Framework. The rules here are Costa Rican and differ from the EU's AEO regime.

A trade operator applies voluntarily, is certified by the Directorate-General of Customs, and is then treated as a trusted, secure link in the supply chain (art. 266). Certification runs four years, is renewable, but renewal must be requested at least four months before expiry — it is not automatic. Any company with more than three years of operations in Costa Rica may apply; the programme is voluntary and free.

	EU AEO	Costa Rica OEA
Legal base	Union Customs Code	Law 7557 + Reg. 44051-H
Validity	Indefinite, monitored	Four years, renewable
Tiers	AEOC / AEOS / C+S	Simplificaciones / + Seguridad
Headline benefit	Reduced controls	Deferred pay, no guarantee

The three things people get wrong

Guidance written for Europe does not transfer here

OEA is not the EU's AEO

Same WCO origin, different rules. Costa Rica runs its programme under Law 7557 (amended by Law 10271) and Regulation 44051-H — not the Union Customs Code. Four-year validity, not indefinite.

OEA means deferred payment, no bond

The headline benefit is deferred payment of the customs debt without a guarantee (art. 267.1). Operators expect to lodge a bond for losses; for importers and exporters that's the opposite of how the status works. See the guarantee question.

It's a four-year obligation

Annual self-assessment, immediate incident reporting, staying current on customs, tax and social-security debts. Miss one and the DGA can suspend for three months — or cancel (art. 268–269 bis).
