LA44ZZ files

A LA44ZZ file is a payment slip (“bordereau de paiement”) sent by a Caisse d’Allocations Familiales (CAF) as plain text. It lists the payments the CAF makes to one recipient, such as a landlord, for several beneficiaries.

This page describes the layout as the parser expects it, from sample files. It is not a specification of the format.

Here is a sample slip with made-up data:

Header

In the file	Read as
CAISSE D'ALLOCATIONS FAMILIALES and the line below	getCafName(), e.g. CAISSE D'ALLOCATIONS FAMILIALES DE DOCVILLE
The street and city lines below the CAF name	getCafAddress(), joined with ,
DATE DE TRAITEMENT : 05 02 2026	getProcessingDate()
The block on the right of NM REFERENCE	getRecipientName() and getRecipientAddress()
NM REFERENCE: 0000000 0001	getReference()
BORDEREAU DE PAIEMENT A.L. DU 03 02 2026	getPaymentDate()
VB TESTFRPP FR76 0000 …, below REFERENCES BANCAIRES BAILLEUR	getBic() and getIban() (without spaces)

The other header fields (NMFP PAGE, NUMERO DE PRODUIT, TYPE DE TRAITEMENT, TEL, NATURE DR) are not read.

Table

The table is framed by lines of 121 dashes. The column headers come first, then one row per payment, then the total. Each row has eight columns separated by ::

Column	Meaning	Read as
REFERENCES LOGEMENT/PRET	Housing or loan reference, often empty	getReference()
NUMERO ALLOCATAIRE	Beneficiary number	getBeneficiaryReference()
NOM DESTINATAIRE	Beneficiary name	getBeneficiaryName()
DATE DEBUT, DATE FIN	First and last month of the period (MM YYYY)	getStartDate(), getEndDate()
MONTANT BRUT	Gross amount	getGrossAmount()
RETENUE	Deduction	getDeduction()
MONTANT NET	Net amount	getNetAmount()

The row below the table, TOTAL :, gives getTotalAmount(). In the sample files, the total is the sum of the net amounts and each net amount is the gross amount minus the deduction; the parser does not check either.

See parsing for how each value is read.
